In this case Ghost isn't going to really help you. When you make major changes like that, you can cause more head aches than not.
If you are a system builder, you should have heard of WinPE. Setup an external HDD with WinPE boot, and store the install files on it. That will speed up the install time by 2 to 3 times.

Good luck
